DAVID SATTLER, OF MIFFLINyOHIO.

Letters .Patent No. 99,112, dated January 25, 1870.

IMPROVEMENT IN FIELD-FENCE The Schedule referred to in these LettersPatent and making part of the sama l ings- Figure 1 is an elevationvoi`my improved brace# panel, and of a portion of a field-fence, showingthe.

application of the brace-panel.

Figure 2 is a plan of the same.

Figure 3 is a cross-section of the same through line x y in fig. 1.

. Figures 4 are front and side views of one of the fence4posts.

Figure 5 is a detail view of a brace-post.

Figure 6 is a detail View of truss cross-piece.

Figure 7 is a plan of brace-panel brace.

The nature of my invention consists in the combination, with a fenceconstructed of trusses and common rails, of a brace-panel of a novelconstruction, whereby any end movement of the fence is prevented, andthe stability of the fence is much increased.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and opel-ation.

In the fence shown on the accompanying drawings, three truss-posts areshown, each differing somewhat, in construction, from the others, andillustrating some prominent features of fence-construction; but- I wishit understood, that I'claim no new invention or exclusive right ineither or any of these fence-trusses,

whether taken alone or in combination, but simply show them incombination with my improved bracepanel, for the purpose of. showing theoperation of said panel, and to show the farming community a suitableconstruction of field-fence, for use in combination with my improvedpanel.

The centre truss is composed of the two posts A A, the brace-posts C G,and the cross-piece D.

In the posts A are out the oblique notches a, which receive thebrace-post G, and the notches b which receive the cross`piece D.'

In the brace-posts G, are eut the notches c, which fit in the notches ain the posts A, and' thus prevent the sliding of the posts down thebrace-post, or the sliding of the brace-post up the notch a, in the postA.

In the cross-piece D is cut the notch d, which fits into the notches aa, in the posts A A, thus preventing any side motion of the bottom ofthe fence.

The several parts of this truss are arranged with respect to each other,as shown in gs. 1, 2, and 3, and are rigidly secured together by nails hh, as shown.

It is readily seen, that by this construction, the only nails thatreceive any strain are those that secure the cross-piece D to thebrace-post A A, where there is but little strain.

In the `truss-post shown at the left end of the fence, the constructionof the post I I' and cross-piece K is the same as that of the post A Aand cross-piece D, in centre truss, but the brace-posts H H are notprovided with notches a a, consequently the strength ot' this trussdepends on the strength of the nails which secure thebrace-posts H H tothe posts I I.

-Iu the truss shown at the right end of the fence, there are no notchesmade in the posts F F or the cross-piece G, but notches are made on theside of the brace-posts E E, from which it is readily seen that thestrength of this truss 'depends almost entirely on the strength of thenailing.

The lower rails, S S, of the fence, rest on pins or clamps, which unitethe lower ends of the posts A A, or may be set on sills or stones, setunder the ends of said posts, or on a block, W, as seen infig. 1.

lhelower rails S S, of each panel, are notched at their ends, so as tolit under the cross-pieces D, and the upper rails It R Q are laid withtheir ends one above the other, between the posts A A, and above thecross-piece D, the spaces between the rails and the ends ofthe fencebeing lilled by wedges U U, as shown.

The last rails N and O, are laid on a line running under'the crossingsof the brace-posts O O, their ends being cut oii obliquely, so as to fitin that position, as seenl in fig. 3, and they are firmly secured inthat position, by wedges T, which also serve to secure the' ends of allthe rails R Q intheir proper position between the posts A A.

The brace-panel shown at right end of fence is composed of the posts MM, which are firmly planted in the ground, and have the dovetail-shapednotches m m made in their 'front faces, into which fit the bars L L,which have corresponding notches,l l, cut at their lower sides, wherethey are secured by nails k lo, as shown. A brace, B, having its endmade with notches c andf, as shown in iig. 7, is placed diagonallyacross the panel M L, thus forming a firm brace for said panel.

'The endof the upper bar L fits under the braceposts E E, wit-h the endof the rail O, where it is secured by the wedges V, while the end of thelower bar L is secnred'between the vrails S S, as shown.

It is readily seen, that by introducing a brace-panel of thisdescription int-o a rail fence constructed as shown, at suitableintervals, it will prevent any danpanel-brace, (it being of the lengthof the other panels,)

rails will be laid upon it by inserting their ends between the ends ofthe rails of the panel on the left, in the spaces occupied by the wedgesU U U Uin fig.

l, and their other ends in similaispaces in the panel on the right.

Bracefpanels may be introduced at such intervals along a line of fenceas may be deemed necessary to give it stability. It is obvious from theconstruction of this brace-panel, that it does not derive its strengthfrom the nails used, but from the manner 'of the framing the posts M M,and the bars L L, and brace B, together, by means of the dovetailednotches; and that the panel-brace cannot yield endwise without backing;

and that a line of fence with it, cannot yield or fall down endwise; andthat it will be especially valuable in lines offence built on hillyground.

Having thus fully described my improved bracepanel and its application,

What I claim as new, and desire to secure by' Letters Patent, is-

The brace-panel M L B, composed of the posts M M, with dovetail-shapednotches m m m m', the bars L L, with notches lll l, and thebrace B, withnotches e and f, the several parts being arranged as described and usedin combination with a rail fence constructed as shown, substantially inthe manner and for the purpose herein specified. l 5 As 'evidence that Iclaim the foregoing, I have hereunto set my hand, in presence of twowitnesses, this 23d day of June, 1868. v
